  1. Actually I forgot to mention 😱, you have to load some fonts before they can be rendered in Image32 (and SVG files only very rarely contain font resources). Image32 reads TrueType fonts both directly from files or indirectly through the OS as demo'ed in SVG101 ... procedure TForm1.FormCreate(Sender: TObject); begin ... FontManager.Load('Arial'); FontManager.Load('Arial Bold'); FontManager.Load('Arial Italic'); FontManager.Load('Arial Bold Italic'); FontManager.Load('Times New Roman'); FontManager.Load('Times New Roman Bold'); FontManager.Load('Times New Roman Italic'); FontManager.Load('Times New Roman Bold Italic'); and make sure you add Img32.Text to your uses clause. Also, you don't need to load a whole lot of fonts, just the ones that you'll need. More info here: http://www.angusj.com/delphi/image32/Docs/Units/Img32.Text/_Body.htm You certainly don't need ImagePanel, that's just useful for displaying images on a form. You can just save images to file if you wish.

    ICS V8.67 announced

    ICS V8.67 has been released at: http://wiki.overbyte.eu/wiki/index.php/ICS_Download ICS is a free internet component library for Delphi 7, 2006 to 2010, XE to XE8, 10 Seattle, 10.1 Berlin, 10.2 Tokyo, 10.3 Rio, 10.4 Sydney and 11.0 and C++ Builder 2006 to XE3, 10.2 Tokyo, 10.3 Rio, 10.4 Sydney and 11.0. ICS supports VCL and FMX, Win32, Win64 and MacOS 32-bit targets. The distribution zip includes the latest OpenSSL 1.1.1i win32, with OpenSSL 3.0 and Win64 versions of OpenSSL being available from the download page. Changes in ICS V8.67 include: 1 - Added support and packages for RAD Studio 11.0. Updated SSL/TLS root certificate bundles, old certificates gone, new ones added, nothing major. 2 - Added support for OpenSSL 3.0 which is a major new release, primarily a lot of internal changes to ease long term support. There is an optional FIPS module with 3.0 but not available here since our DLLs are not built to the standards required for certification. The old engines for special extensions are replaced by new more versatile providers of which the FIPS module is one, a provider legacy.dll has obsolete ciphers and hash digests, including MD2, MD4, Blowfish, DES, IDEA, RC2, RC4, SEED, that most applications no longer need and which needs to loaded by the application by setting global variable GSSLEAY_LOAD_LEGACY to true before loading OpenSSL. 3 - OpenSSL 3.0 does not offer any specific new features of benefit to ICS at present, although HTTP/3 support is planned for 3.1 or later, so the main ICS distribution retains OpenSSL 1.1.1i which is fully supported until September 2023. OpenSSL 3.0 may be downloaded from the download page. There are two global variables to restrict which OpenSSL version is loaded, GSSLEAY_DLL_IgnoreNew set true will ignore 3.0, while GSSLEAY_DLL_IgnoreOld will ignore 1.1.1, if both sets of DLLs are available in the same directory. The main SSL samples all set these globals, which can be changed for testing one version or the other, or set by the application, but must be before OpenSSL is initialised. 4 - The main implication for ICS with OpenSSL 3.0 is for SSL/TLS certificate private keys saved with password protection, which is required for PKCS12 certificates for importing into the Windows certificate store. The new PKCS12 default password encryption AES256 is not recognised until Windows Server 2016 v1709 and Windows 10 v1709, so Server 2012, Windows 10 RTM and earlier won't load AES passworded keys, only 3DES, for which the legacy.dll must be loaded. 5 - The TX509Base class has various improvements. The ValidateCertChain method reports CA roots for multiple certificate verification paths with two or more intermediate certificates, rather than only the last. The CertMainInfo method provides a single line with the main certificate information. 6 - There are two new classes to write and read SSL/TLS certificates to and from the Windows Certificate Store, including private keys. This is primarily so Let's Encrypt certificates can be installed automatically for use with the IIS web server. TMsX509List descends from TX509List adding a method LoadFromStore to load the list from a Windows certificate store by store name TMsCertStore and location MsCertLocation. For My/Personal store, attempts to load private keys if they are allowed to be exported unencrypted. TMsCertTools descends from TSslCertTools adding methods SaveToStorePfx and LoadFromMyStore to access Windows certificate stores. Note access to the Local Machine Store for web server certificates requires administrator rights. 7 - Various improvements for the OverbyteIcsPemTool sample. It includes new buttons to list the contents of Windows certificate and private key stores and allow old items to be deleted. This may be useful for cleaning up old certificates and private keys from the Windows stores. Added ResavePrivateKey and Resave Private Key menu option which prompt for a PFX or PEM file containing an encrypted private key with a new cipher, renaming old file to .oldpem/pfx. Specifically for files saved with old ciphers than OpenSSL 3.0 does not support as standard if required for older versions of Windows. Displaying certificates and bundles is no longer a new modal window, but updates the existing log window. Improved import certificates from Windows certificate store to use TMsX509List instead of Windows API calls, and to access all Windows store locations instead of just user, specifically the Local Machine store where server certificates are located. 8 - For the TX509Certs component, the default cipher for encrypting PFX/P12 files is now PrivKeyEncAES256 with 3.0 unless the legacy DLL is loaded when still PrivKeyEncTripleDES so older versions of Windows can load them. Changed extraction of download PEM bundle so that main certificate does not need to be first in file, log them all, and ignore any self signed root certificates. If testing dns-01 challenge fails, rotate to next public server and three retries (previously only happened on timeout). When saving files with private keys, log encryption type used. Added more certificate output formats, OutFmtPwPem and OutFmtPwP12 specify whether to password PEM and P12/PFX private keys. Note Windows always needs passworded P12/PRX files, while Apache web server only accepts PEM files without a password. Allow automatic installation of new certificates to the Windows Certificate Store so they can be used by IIS web sites, by setting output format to OutFmtWinStore. Note application must have administrator rights to do this. 9 - Fixed two problems in the FTP client, support option ftpFixPasvLanIP for PUT/APPE uploads as well as downloads, and support IPv6 for PUT/APPE uploads as well as downloads. 10 - Fixed a problem in TIcsMailQueue with sequential number generation to avoid file locking errors and unicode BOM corrupting file, generate large random number for errors instead of reverting to 1. Don't save BOM withunicode compilers. 11 - In the Application Web Server TSslHttpAppSrv, added an optional LastModified parameter to the AnswerStream, AnswerPage, and AnswerString methods to avoid adding a custom header line with the date. Added NO_CACHE_EX and NO_STORE_EX literals. Added PUT and DELETE verb handlers, similar to GET and POST. 12 - For the HTTP client TSslHttpCli, fixed a relocation problem where the Location: header included a path with a space, encode the space. Fixed another relocation problem where HEAD sometimes stalled. Remove # fragment or anchor from URL in relocation, only used by browsers and not by servers. 13 - In the TIcsBlackList component, Internally use BlockedFlag instead of setting attempts to 9999 once the actual maximum failed attempts is reached, so we can keep counting attempts. 14 - Added a new SSL sample, OverbyteIcsDDWebService.dpr which is very similar to OverbyteIcsSslMultiWebServ.dpr, but designed as a Windows service, although it will also run as a GUI for debugging. It requires DDService service framework to be installed from https://www.magsys.co.uk/delphi/ddservice. asp. It also includes a REST server with simple lookup responses from a SQL database, which optionally requires DISQLite3 5.36.5 or later to be installed from http://www.yunqa.de. Note this sample in not in the project groups due to these pre-requisites. 15 - Moved TRestParams from the OverbyteIcsSslHttpRest unit to OverbyteIcsUrl to ease circular references. Added a new method AddItemNULL to add a null, in Json this will be unquoted. Added a new TRestParamsSrv component which provides methods for creating REST server Json responses from a SQL database resultset, one or more rows, also error responses. Note this is only compiled if DATABASE is defined in OverbyteIcsDefs.inc to avoid bringing in database units that are not available on all Delphi editions. There is a REST server sample OverbyteIcsDDWebService.dpr that illustrates SQL lookups. 16 - In the proxy component TIcsHttpProxy, don't send an HTTP request header until after HTTP body has been processed in case the body length changes. HTTP Forward Proxy using HTTP works again, broken in V8.65. Using HTTP Forward Proxy, convert absolute URL to path only since some servers can not process an absolute URL and sulk. 17 - In the Jose unit, rewrote the functions converting private keys to and from Json Web Keys with new OpenSSL 3.0 provider functions. Use AnsiStrings and functions when dealing with binary data to avoid possible issues with string conversions and nulls. Json now created with TRestParams. 18 - Added two new sample project groups, OtherDemos64 and SslDemos64 which include Win64 versions of all the main active samples with 64 added to the project name, so they can be regularly built alongside the Win32 versions without changing platforms and overwriting executables.

    Let's Encrypt old root expiry and OpenSSL

    After investigation, the main issue today was with the Windows IIS web server using Let;'s Encrypt certificates. The Windows Intermediate Certificate Authorities store had old certificates that it was still sending out with each request, according to the excellent SSL Labs test site. Essentially, you only install new certificates in the store and old ones remain until removed manually using Admin Tools, Manage Computer Certificates, or the latest version of the ICS PemTools sampl;e which also allows deletion of certificates, which can now be done from applications as well. IIS then sends any intermediates it finds matching for the server certificate. Browsers seem cleverer than OpenSSL in ignoring unwanted certificates, so the problem may not be that visible. My IIS server has IPv4 and IPv6 binding on several IP addresses, and the issue did not appear on all bindings, possibly due to caching. I had to reboot the server after deleting the unwanted certificates to stop IIS sending them, even after restarting IIS itself. So if you have installed Let;'s Encrypt certificates into the Windows store, I'd recommend you deleted these old intermediates: Issued to CN: R3, (O): Let's Encrypt Issuer (CN): DST Root CA X3, (O): Digital Signature Trust Co. Expires: 29/09/20213 Issued to (CN): Let's Encrypt Authority X3, (O): Let's Encrypt Issued by (CN): DST Root CA X3, (O): Digital Signature Trust Co. Expires: 17/03/2021 16:40:46, Issued to (CN): ISRG Root X1, (O): Internet Security Research Group Issuer (CN): DST Root CA X3, (O): Digital Signature Trust Co. Expires: 2024-09-30T18:14:03, The last one is still being distributed by Let's Encrypt with new orders, and needs a change to ICS to remove it, but does not seem to give an error with OpenSSL. Angus

    ICS V8.67 announced

    I took a glance on adapting message loop for Linux but ICS' wrapper is too complex to understand it quickly. I've no strong requirement for Linux currently - even if it appears, Wine is doing pretty well. Nevertheless, would be nice to have Linux natively.
  6. @angusj Thank you so much! The font manager works like a charm!

    Changing names to match new OpenSsl dlls

    Sorry, your proposed changes would require change to all ICS applications using SSL, due to the change of a unit name and various function names, ICS is always designed to be backward compatible so that most applications can be easily rebuilt with new versions without numerous errors to fix.

    Correct. Most UIs for git visualize branches and merges.
